Total Risk in CT Imaging: Why Clinical Risk Outweighs Radiation Risk with Dr. Francesco Ria

Radiation risk has long shaped how clinicians and patients think about CT imaging. But according to Dr. Francesco Ria, focusing on radiation alone misses the bigger picture. In this episode of Rethink Imaging, Dr. Ria introduces the concept of “total risk” — a framework that considers not only radiation exposure, but also the clinical consequences of missed or delayed diagnoses, unnecessary repeat scans, suboptimal image quality, and inappropriate utilization. When CT exams are avoided out of disproportionate fear of radiation, patients may face far greater harm from undiagnosed disease. Dr. Ria explains how advancements in CT technology, protocol optimization, and evidence-based imaging guidelines have significantly reduced radiation dose over time. Yet public perception and even some clinical decision-making still reflect outdated assumptions about risk. He argues that imaging professionals must communicate risk more clearly and contextualize radiation within the broader clinical picture. The discussion also explores the responsibility of medical physicists, radiologists, and technologists in balancing image quality with dose, ensuring protocols are clinically appropriate, and aligning imaging decisions with patient-centered outcomes. Rather than asking, “How low can we go?” the better question may be, “Is this exam delivering the right information at the right time for this patient?” Ultimately, this episode reframes CT safety as a multidimensional challenge — one that requires leadership, education, and collaboration across the healthcare system to ensure patients receive the diagnostic clarity they need without unnecessary compromise.
